Sintered Glass Gooch Crucible

PISCO® Sintered Glass Gooch Crucibles are high-precision laboratory filtration vessels manufactured from high-grade low expansion borosilicate glass. Designed specifically for gravimetric analysis and residue determination, these crucibles incorporate a sintered glass filter at the base, eliminating the need for separate filter paper and reducing contamination risk. Their excellent thermal stability and chemical resistance make them ideal for use in acidic, basic, or high-temperature environments.

Available in various capacities and porosity grades (G-0 to G-5), PISCO® Gooch Crucibles ensure consistent filtration and collection of precipitates during laboratory procedures. Each crucible is manufactured to conform with international quality standards such as ASTM, ISO, and B.S., ensuring precision and reliability in every application. These crucibles are suitable for analytical chemistry, environmental testing, pharmaceutical labs, and research institutions where accurate mass measurements and residue analyses are essential.
